Frequently Asked Questions
How does a RFID reader work?
A RFID reader produces an alternating magnetic field at frequencies of 125/134.2kHz (LF) and 13.56MHz (HF). This field is used to supply energy to one or more transponders (media) within its range. At the same time, the field facilitates data transfers between the reader and transponder.
How are RFID systems used?
RFID technologies are used in many areas, including identification of individuals (e.g., employee identification cards, personal identification cards, passports, etc.), animal identification, contactless payment, time tracking, access control (e.g., door locks, turnstiles, lockers, ski lifts, etc.), product labeling, article surveillance (e.g., theft prevention), product tracking, lifecycle management, the IoT (Internet of Things), fleet management and car sharing.
What are the benefits of RFID?
RFID transponders do not require line-of-sight propagation to read or write. RFID is comparatively wear-free, that is, it does not suffer any contact-generated wear (this is the case for both the reader and transponder) compared with reading problems experienced by contact EC cards or swipe cards. Unlike printed barcodes, data can be written on many RFID tags. RFID is also capable of withstanding environmental conditions like the wind, weather, UV radiation and soiling. RFID provides a scalable degree of security (e.g., from simple read-only tags to high security transponders evaluated by EAL/common criteria).
What is the range of RFID readers?
The range depends on the transponder, the reader and the ambient conditions and will typically be between 2 and 10 cm. Custom-designed versions permit ranges of up to 25 cm. The relatively short range can be viewed as a clear affirmative action by an individual. For instance, a door lock will not release until the user has placed his or her ID directly in front of the reader. It will not do so unintentionally when the user simply happens to pass by it.
What is the difference between RFID and NFC?
RFID is an overarching term, and NFC is a potential usage technology – RFID is fruit, and NFC is a pear. NFC is based on RFID technology. NFC is primarily used in many cell phones for such purposes as: payment, online banking, access control, IoT, smart posters and connection handover, e.g., from NFC to WLAN/Bluetooth.
